Re: wiper motor help!

What vehicle is the wiper motor from? The red & black will be +12 and ground respectively, the grays may be a park switch, or may be 2 different speeds. Put 12v power to it and experiment.

If you run it from a 5-10 amp battery charger and connect a short, you probably won't harm anything, just don't leave it on too long.
